General Description: The Freshwater (or FW) Koi Angelfish is a color morph from the wild Silver ‘scalare‘ angelfish that has a large distribution across many river systems in South America. It is rare to encounter wild freshwater angelfish in the hobby, because they are now mass produced in captive-settings in Asia. For our store specifically, the majority of our freshwater angelfish are sourced locally from hobbyists right here in Wisconsin! Angelfish may be one of the most popular freshwater fishes in the hobby because of their elegant appearance, personality, numerous color morphs and compatability. Do not forget that they are cichlids however, as these behaviors can become more obvious in peaceful community-type aquariums, particularily during breeding. Koi angelfish are extremely variable in their appearance. The term “koi” specifically refers to the mottling of black and white coloration, which is accompanied by bright orange to yellow patches of coloration. Your individual Koi angelfish will be one of a kind! Angelfish are somewhat social and if acquired as juveniles, they are best kept in small groups of at least 4 to 6 individuals. The body of an adult Koi angelfish can reach a size of approximately 6″ across, but they can be 8″ or taller in height once you account for their dorsal and anal fins. Angelfish, at any size, are difficult to sex unless they are in spawning behavior.
Diet Requirements: Freshwater angelfish are far removed from their wild ancestors, therefore accepting most foods with no issue. A diet made up of various high quality vegetable based and protein based flake foods and sinking pellet foods are ideal, in addition to offering frozen foods such as bloodworms, brine shrimp, daphnia or any other mixed freshwater preparations. Variety is the spice of life in order to maintain color, immune function and longevity of your fish.
Care Requirements: An established minimum 55 gallon aquarium is ideal for a small group of juvenile Freshwater koi angelfish. A larger group will require a bigger aquarium and the tank may need to be upgraded accordingly as the angelfish grow and pair off. Because of their size potential in terms of height, it is important to consider a generously tall aquarium footprint. For those looking to keep only a pair of juvenile angelfish, we recommend nothing less than a 30 gallon aquarium for these cichlids. Freshwater angelfish are intolerable of nitrite or ammonia spikes, and should not be introduced into a newly set-up aquarium. Biweekly water changes are encouraged to keep water parameters favorable (Nitrates < 30 ppm). Our tank-raised angelfish have a range of water parameters in which they can adapt to, but all prefer gentler water flow. The aquarium does not need to be aquascaped with anything in particular, but driftwood and other natural-looking arrangements will bring out the beauty of these angelfish. Freshwater angelfish have been observed to show exceptional coloration in aquariums that are well planted (live). Plants that grow taller, such as Amazon Swords (Echinodorus sp.), are a favorite. Incorporating flat surfaces, such as slate rock, will provide natural spawning areas for your angelfish once they’re able to breed. Koi angelfish are overall relatively peaceful toward most tank mates, but they can squabble with each other. You can house different color morphs together successfully. Incompatible species that would harm angelfish and their decorative fins include, but are not limited to, Puntius barbs (Tiger, Black Ruby, Green Tiger), African cichlids, most Central American cichlids, and certain livebearers. Recommended water conditions, 76-86° F, KH 2-15, pH 6.0-7.5.
